VMS 250 Static
Batch Measurement | 1D and 2D | British Manufactured
Built on the patented Vertex VMS platform, the VMS 250S is a static digital height gauge designed to deliver highly accurate, repeatable precision measurements from a dedicated granite-based measuring station.
- Static granite-based measuring station: The Vertex VMS 250S is a compact, self-contained version of the Vertex VMS digital height gauge, permanently mounted on its own dedicated granite base for maximum stability and repeatability.
Using the same patented air-bearing, non error-mapped design as the wider Vertex range, it provides high-accuracy height measurement equipment for manufacturers who require dependable, repeatable results in a fixed inspection setup. - Optimised for repeatable batch inspection: Because the gauge and reference surface remain permanently aligned, the VMS 250S removes the setup variation that can occur when instruments are moved between different granite plates or inspection stations.
This makes it particularly well suited to production cells and inspection benches where the same family of parts is measured repeatedly, and where speed, consistency and ease of use are critical to efficient workflow. - Flexible 1D and 2D software configurations: 1D measurement software is available with the VMS 250S Series 9, with a future upgrade path to 2D capability, or as Series 10 where 1D and 2D measurement routines are enabled from the outset. This allows users to match the software capability of their digital height gauge to current inspection demands while retaining flexibility for future measurement requirements.
- British-engineered reliability and assurance: Like the wider Vertex platform, the VMS 250S benefits from air-bearing technology, UKAS calibration support and the robust engineering heritage of Eley Metrology. Designed and supported in the UK, it provides a reliable long-term solution for controlled inspection environments where measurement repeatability and process efficiency are a priority.
- Batch measurement of small components where repeatability and setup consistency are essential.
- 1D height measurement, including heights, step heights, gaps, slot widths and centreline-to-centreline distances.
- Internal and external diameter measurement on small precision-engineered parts.
- Repetitive inspection tasks in production cells or dedicated inspection benches.
- 2D measurement applications, when enabled, including perpendicular distances, PCD or bolt circles, and simple feature-to-feature relationships.
- Precision measurement in manufacturing, quality control and engineering environments where a self-contained measuring station is preferred.
The Vertex VMS 250S is backed by Eley Metrology’s after-care support package, including operator training, technical assistance, servicing and repair support from an experienced UK-based team.
UKAS calibration is available both on-site and in the laboratory, helping maintain the accuracy, compliance and long-term reliability of your precision metrology equipment.
This support structure helps ensure the VMS 250S continues to deliver dependable precision measurements throughout its operational life, while protecting the long-term value of your height measurement equipment investment.

FAQs
Can the VMS 250S be supplied as Series 9 (1D) or Series 10 (1D+2D)?
Yes. Mechanically, the 250S is the static form factor of the Vertex VMS; electronically, it can be configured with the Series 9 1D software (with 2D upgrade path) or with Series 10 software where 2D routines are enabled from day one. This lets you align the software capability with your current and future measurement requirements without changing the core hardware.
Why choose the VMS 250S over other Vertex models?
Because the VMS 250S is fixed to its own granite base, it eliminates setup variation between different surface plates and provides a stable, repeatable station ideal for batch measurement. It’s particularly well‑suited to production cells or inspection benches where the same family of parts is measured repeatedly and speed, repeatability and ease of use are critical.
What types of measurement is the VMS 250S best for?
The 250S excels at 1D measurements such as heights, step heights, ID/OD diameters, gaps, slot widths and centreline‑to‑centreline distances on small components. The Series 10 VMS 250S provides 2D measurement capability, allowing it to also handle perpendicular distances, PCD/bolt circles and simple 2D feature‑to‑feature relationships for more complex parts.
What calibration and support options are available for the VMS 250S?
Eley provides both on‑site and laboratory UKAS servicing and calibration of various digital height gauges, which includes perpendicularity checks, air‑bearing inspection and full performance verification. Ongoing support includes operator training, telephone/email technical assistance and access to spare parts and software updates to keep the station productive over its full lifetime.
What’s the difference between a VMS 250S and a VMS 250?
Both share the same measurement platform, but the VMS 250 is a mobile gauge intended to be used on a granite surface table and attached with a dual probe holder, whereas the VMS 250S is a static system fixed to its own granite base including a singular probe holder. The 250 is ideal where flexibility and portability between plates is needed; the VMS 250S is the better choice where a dedicated, high‑throughput measuring station is required.
What environment does the VMS 250S need to perform at its best?
Like all Vertex gauges, the 250S performs best on a stable 18–22°C shop‑floor or inspection‑room environment with low vibration, clean air and controlled humidity. The granite base and air‑bearing system are designed to deliver long‑term stability in both production and inspection settings when kept clean and properly maintained.
How does the fixed granite base help in batch measurement?
A dedicated granite base keeps the gauge and reference surface permanently aligned, so operators are not moving the instrument between different surface plates or tables. This reduces setup time, removes a major source of variation, and supports consistent results when measuring repeated batches of the same or similar parts.
How should I maintain a VMS 250S station used for batch measurement?
Keep the granite base and air‑bearing contact surfaces clean, wiping away dust, swarf and coolant, and follow a regular cleaning schedule using suitable fluids. You can schedule annual (or more frequent) UKAS service and calibration of your digital height gauge to maintain performance in high‑volume environments.
Do I still need a separate granite surface plate with the VMS 250S?
No additional granite surface plate is required for the gauge itself. The VMS 250S is supplied on its own dedicated granite base, which acts as the reference surface. You may still choose to use separate granite surface plates elsewhere in your process, but the VMS 250S measuring station is self-contained and optimised for its own base.
